What are Montresor's fears in "The Cask of Amontillado"?

Montresor's greatest fear in "The Cask of Amontillado" is
that he will be caught during his crime and be incarcerated for murder. So, he
painstakingly details every facet of his plot against Fortunato. He fears that his
servants may witness his actions, so he makes sure they will be enjoying the carnival
festivities instead. He worries that Fortunato may not follow him into the catacombs, so
he tempts him with a bottle of rare amontillado. Montresor fears that a quick murder
will not do justice for the crimes committed against him, so he concocts a way to
satisfactorily torture Fortunato emotionally as well. He worries that Fortunato's cries
may be heard, but the depths of the catacombs will solve this problem--as well as any
qualms about whether the body will ever be found.
